TLZ9V1-GS18 Equivalent & Substitute Parts

Part Overview

The TLZ9V1-GS18 is an active-status zener diode manufactured by Vishay General Semiconductor - Diodes Division. This component is a 9.1 V, 500 mW surface mount zener diode in SOD-80 MiniMELF packaging, designed for voltage regulation and protection applications in electronic circuits. The part is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when the original manufacturer part becomes unavailable, inventory is depleted, or alternative sourcing is required while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLZ9V1-GS18 is determined by the following critical parameters:

Electrical Compatibility:

• Zener voltage nominal value of 9.1 V
• Maximum power dissipation of 500 mW
• Forward voltage characteristics suitable for 200 mA operation

Mechanical Compatibility:

• Surface mount packaging in SOD-80 MiniMELF form factor
• DO-213AC case designation
• Identical footprint and lead configuration

Regulatory & Environmental Compliance:

• ROHS3 compliance requirement
• MSL 1 moisture sensitivity rating
• Operating temperature range support

The substitute part CLL5239B TR PBFREE meets all these criteria, providing functional equivalence while maintaining the same electrical performance envelope and physical form factor.

Engineering Selection Recommendations

Primary Selection: TLZ9V1-GS18

The TLZ9V1-GS18 is the original manufacturer part from Vishay General Semiconductor - Diodes Division. This component is active-status and ROHS3 compliant. Selection of this part is appropriate when inventory availability and direct manufacturer sourcing are feasible.

Substitute Selection: CLL5239B TR PBFREE

The CLL5239B TR PBFREE from Central Semiconductor Corp is an active-status equivalent suitable for direct substitution. This part maintains identical zener voltage (9.1 V) and power rating (500 mW) with the same SOD-80 MiniMELF package. The substitute exhibits improved forward voltage characteristics (1.25 V versus 1.5 V at 200 mA) and extended operating temperature range (-65°C to 200°C versus -65°C to 175°C). Both parts are ROHS3 compliant with MSL 1 rating. The impedance specification of the substitute (10 Ohms maximum) is within acceptable tolerance relative to the primary part (8.5 Ohms maximum). Selection of this substitute is appropriate when the primary part is unavailable or when the extended temperature range is beneficial to the application.

Frequently Asked Questions (FAQ)

Q: Can the CLL5239B TR PBFREE be used as a direct replacement for the TLZ9V1-GS18?

A: Yes. Both parts share identical zener voltage (9.1 V), power dissipation (500 mW), and SOD-80 MiniMELF packaging. The electrical parameters fall within compatible operating ranges for standard voltage regulation and protection applications.

Q: What is the difference in impedance between these parts?

A: The TLZ9V1-GS18 specifies 8.5 Ohms maximum impedance, while the CLL5239B TR PBFREE specifies 10 Ohms maximum. This 1.5 Ohm difference is within typical circuit tolerance margins for zener diode applications and does not affect functional compatibility.

Q: Does the substitute part have a wider operating temperature range?

A: Yes. The CLL5239B TR PBFREE operates from -65°C to 200°C, compared to the TLZ9V1-GS18 range of -65°C to 175°C. The substitute provides an additional 25°C of upper temperature capability.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLZ9V1-GS18 and CLL5239B TR PBFREE are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the significance of the ±5% tolerance specification on the substitute part?

A: The CLL5239B TR PBFREE carries an explicit ±5% tolerance rating on the zener voltage. This tolerance specification defines the acceptable variation range around the 9.1 V nominal value. The primary part does not list a tolerance specification in the provided data.

Q: Are the packaging and footprints identical?

A: Yes. Both parts use DO-213AC, MINI-MELF, SOD-80 packaging with identical surface mount footprints and lead configurations, enabling direct PCB-level substitution without layout modifications.
